First half of the year I got in semesterized math (this years and next years math course, except both done in half a year one after the other)
I finished this years math course, got out of that math class with an 80% average and got back into the math class I just finished, halfway through the year. I'm done everything in the class, have every note wrote down/all of the examples and any other stuff in my binder, with my final grade for the course being 80%. I don't know how or why the forget they allowed me to do it, but because I'm in this course even though I already have a final mark for it, I literally do nothing in math anymore. The teacher occasionally gets pissed at me for sitting around doodling or whatever, but I have to do absolutely none of the work. It's loving brilliant.
I'm also not slowed down by getting out of the semesterized math course. Because I have the average from the course this year I can get into accelerated math next year and then do pre calculus before university. IE the same path I was on with the semesterized course.
